  225The Mineral Industry of 
Kentucky 
By Donald K. Harrison1 and Preston McGrain2 
 The value of Kentucky's nonfuel mineral production in 1978 and 1979 was
$191.3 million and $207.9 million, respectively. Stone continued as the leading
nonfuel mineral commodity produced, accounting for 56% of the State's total
nonfuel mineral value. Other commodities produced were cement, clays, sand
and gravel, and lime. Small quantities of zinc and lead were produced as
a byproduct of the fluorspar industry in 1978. Commodities imported for processing
included perlite and vermiculite. In 1979, the State ranked fourth in the
Nation in production of primary aluminum. During the biennium, output of
construction materials (sand and gravel, stone, and cement) was above 1977
levels, primarily because of increased construction activity in the State.
 Trends and Developments.—Cominco American Corp. continued to explore
prom- 
ising zinc-bearing formations in southcentral Kentucky. After extensively
evaluating mineral deposits and national economic conditions, the company
will determine whether development is feasible. Although local groups are
optimistic about the development of a large mining complex in thin area,
company officials have taken a more cautious view. 
 ASARCO Inc. has indefinitely postponed previously announced plans to build
a $100 million zinc refinery complex near Stephensport, in Breckinridge County,
mainly because of environmental constraints and increased operating costs.
 Anaconda Aluminum Co. completed an $80 million addition to its aluminum
reduction plant at Sebree. however, most aluminum producers curtailed expansion
plans, even though existing facilities were operating at near-peak capacity.
